A journalist in the United States has lifted the lid on one of the most pressing dilemmas of the modern workplace.
Amanda Terkel, Huffpost's Washington bureau chief, tweeted a passive-aggressive note spotted in her office bathroom, detailing in excruciating detail why an unknown person should stop urinating on the toilet seat.
The hilarious printout dissected all the possible reasons for accidentally sprinkling pee on the toilet seat, including the advice: "If you're afraid of germs, please Google how sitting on the seat is the least of your worries."
For those playing at home, it is widely accepted by microbiologists that infectious agents cannot be transmitted by sitting on a toilet seat.
